6 Best Models That Work with Janitor AI, Free and Paid

Janitor AI is a character-rich roleplay chatting model. You can connect it with different AI models. The model you choose decides the quality of your experience. These models give it the power to chat, roleplay, and create stories. Some are free. Some are paid. In this blog, you will see the 7 best models that work with Janitor AI. So that you can pick the right one.

Why Janitor AI Needs Models

Janitor AI is an interface.
It does not generate text by itself.
It connects with models like LLaMA, GPT, or Falcon.
The model does the “thinking.”
Janitor AI gives you characters, memory, and roleplay tools.

1. LLaMA 2 (Free)

Made by Meta (Facebook).
Open-source and free.
Comes in sizes: 7B, 13B, and 70B parameters.
Strong at roleplay and storytelling.
Can run on local PCs with a GPU or on Google Colab
Works with Janitor AI through Kobold AI or API.
Janitor AI ( User Interface) + Kobold AI (Middleware) + LLaMA 2 ( Brain).
Janitor AI doesn’t generate responses on its own. It is just a UI that collects your input.
Kobold AI provides extra features to janitor AI, like storytelling and story writing. It also acts as a Middleware or bridge that connects the Janitor with a backend Model like LLaMA 2.

Best for: Free users who want realistic chats and long roleplays.

2. Mistral 7B (Free)

It is an open-source model made by Mistral AI.
Small but powerful.
Free to use.
Fast and lightweight means it operates with 7 billion numbers (parameters)
Hardware: Mid-range GPU or cloud service.

Best for: Fast replies and low hardware cost.

3. Falcon 40B (Free)

Falcon 40B was developed by the Technology Innovation Institute (TII).
It’s completely open-source, allowing anyone to use it.
With 40 billion parameters, it’s one of the larger free models available.
Compared to smaller models like Mistral 7B, it runs more slowly, but the trade-off is better performance and more detailed answers.
The large size means it needs to handle a huge amount of data, which makes it heavier to run and requires a capable PC or a cloud server.

What the size means in practice

The 40B parameters allow Falcon to:
Understand complex writing styles.
Keep track of longer conversations.
Produce well-structured and detailed responses.
Because of this, it’s popular for
- creative writing,
- branching stories, and roleplay.

Hardware Requirements

GPU: 40GB VRAM (NVIDIA A100).
RAM:64GB
Memory:200–250GB.
Prefer cloud platforms if your PC can’t handle it.
Best for: Users who want depth in roleplay and are okay with slower responses in exchange for richer conversations.

4. GPT-J 6B (Free)

Older model, but still useful.
Open-source and free.
6B parameters.
Lightweight compared to Falcon 40 B.

Run with ~12–14 GB VRAM (FP16).
Run with ~8 GB VRAM using 4-bit quantization.
Store model size ~12–15 GB.
Work on mid-range GPUs (RTX 3060/3070

Can run on consumer GPUs.
Supports basic roleplay and story prompts.
Best for: Beginners testing Janitor AI with free models.

GPT-6B And Falcon 40B Comparison

Feature	GPT-6B (lightweight)	Falcon-40B (heavyweight)
1. Parameters	6 billion	40 billion
2.VRAM(FP16)	12-14 GB	80 GB
3.VRAM(4 bit quant)	8 GB	48-60 GB
4.Model size(disk)	12-15 GB	90-100 GB
5. Speed	Fast on user GPUs	Slow without server GPUs
6. Hardware needed	Mid-range GPU (RTX 3060/3070)	Multi GPU setup or enterprise GPU(A100, H100)
7. Output quality	Basic, good for casual chat and roleplay	High, strong reasoning and coherence

5. GPT-4 (Paid)

Built by OpenAI.
Very powerful and accurate.
It runs on heavy server-grade hardware.
GPT-4 is slower in raw speed than lightweight models like GPT-J 6 B.
It delivers high accuracy, reasoning, and coherence
Architectural upgrades make it faster and more reliable.
It processes more than 175 B parameters
Paid access through the OpenAI API.
1. Usage-based rates via API
Handles roleplay, reasoning, and long context.
Works with Janitor AI via API connection.
Has the best quality text generation.
Used to solve advanced problems.
Best for: Users who want premium, natural, human-like chats.

6. Claude 2 (Paid)

Made by Anthropic.
Paid API access.
Known for safe and long context chats.
1. It can store and process long documents without splitting them in parts.
Handles 100k tokens in one go.
1. A 100k token means it can process 75000 words in a single conversation.
Strong in roleplay with memory support.
Easy integration with Janitor AI.

Features

Needs powerful cloud GPUs (like NVIDIA A100/H100).
Uses very large RAM (hundreds of GB).
Has around 70–100 billion parameters(exact number not public).
Can’t run on a normal PC, only on Anthropic’s servers.
Best for: Long, detailed roleplays with safety filters.

How to Choose the Right Model

Features	Model
Low budget	1.LLaMA 2 2. Falcon 3. Mistral 4. GPT-J
1. High quality 2.No hardware	1. GPT-4 2. Claude.2
1. Cheao 2. Fast	GPT-3.5 Turbo

Final Thoughts

Janitor AI gives you fun chats, roleplays, and stories. But the model you connect decides the quality. Free models like LLaMA 2 and Mistral are great if you want to save money. Paid models like GPT-4 and Claude 2 give the best results

So, the best choice depends on your budget and your needs
